BBC Sky at Night magazine review 4.4 out of 5 stars and said, "it is the mark of a good manufacturer when we find ourselves often saying how enjoyable it is to use its mounts, and Celestrons CGEMII is no exception. Well designed and engineered, eay to operate with great tracking for both visual and imaging purposes, the CGEMII is highly recommended in its own right, or as an upgrade from a CG4 or AVX."
ERGONOMIC DESIGN
CGEM II was designed to be ergonomically friendly with large Altitude and Azimuth adjustment knobs for quick and easy polar alignment adjustment. The internal RA and DEC motor wiring provides a clean look and an easy and trouble free set up.
INNOVATION
The CGEM II series features Celestron’s innovative All-Star Polar alignment procedure. All-Star allows you to accurately polar align the mount using any star, even ig the celestial pole cannot be seen. Another great feature of the CGEM II sure to please astroimagers, is the Permanent Periodic Error Correction (PEC) which will allow users to train out the worm gears periodic errors, while the mount retains the PEC recordings.
PERFORMANCE
For objects near the Meridian (imaginary line passing from North to South), the CGEM II will track well past the Meridian for uninterrupted imaging through the most ideal part of the sky. The CGEM II mount has a robust database with over 40,000 objects, 100 user defined programmable objects and enhanced information on over 200 objects. Celestron's CGEM II mount is the perfect fit between the Advanced VX Series and CGX Series.
